Hitachi Construction Machinery ZX160LC Parts Catalog

I’ve watched guys spend half a day cross-referencing aftermarket part numbers, only to find the seal kit doesn’t fit the rotary group. That’s time you don’t get back. The Hitachi Construction Machinery ZX160LC Parts Catalog is what you put on the bench when you need the exact factory part number, the correct exploded view, and the interchange codes that tell you if a superseded part works. No guesswork.

206 Pages of Factory Part Numbers

Two hundred and six pages. That’s what Hitachi originally printed for the ZX160LC. Every page is a direct scan of the Japanese-English bilingual catalog that the dealer network uses. The contents start with COVER and CONTENTS, then break into four main sections: PUMP, MOTOR, VALVE, and CYLINDER. Each section is split into sub-sections that mirror the actual hydraulic groups on the machine. No reprints, no third-party transcriptions—this is the original PDF from Hitachi’s publication number 78214020599.

Valve Section: 8 Sub-Sections for Control Valve

If you’ve ever rebuilt a control valve on a ZX160LC, you know there are more spools, springs, and plugs than a parts counter can keep straight. This catalog dedicates eight sub-sections to the control valve alone: CONTROL (1/8) through CONTROL (8/8). Then it adds separate entries for the relief valve, pilot valves (front/swing, travel, and general), solenoid valve, shuttle valve (with five sub-sections), lock valve, slow-return valve, and selector valve. You get the part numbers for every Valve component down to the O-ring.

Pump and Motor Breakdown – Piston, Control Group, Rotary

The PUMP section covers the piston pump, control group, regulator cover part, and two rotary groups (D and I). The MOTOR section includes the oil swing motor, travel devices (in two parts), and the T. mission. Each exploded diagram shows the exact orientation of seals, bearings, and spacers. When ordering a travel motor rebuild kit, you can match the part number from the book against what’s on the machine tag—no need to pull the whole unit just to check a number.

Cylinder Assembly Variants: Boom, Arm, Bucket, Positioning

This catalog covers every cylinder variant Hitachi offered for the ZX160LC. Boom cylinders are separated by right and left, with holding valve options for mono boom and 2-piece boom. Arm cylinders list separate entries for mono boom and 2-piece boom, again with or without holding valves. Bucket and positioning cylinders are included, plus the holding valves for each. The parts index at the back lets you cross-reference any part number across all sections.

Source Validity: Why OEM Beats Aftermarket

I’ve torn more shims out of aftermarket cylinder rebuilds than I can count—wrong thickness, wrong material. This catalog is the same one Hitachi supplies to their own service network. The interchange codes (Y, I, P, D, K, R, S, OP, OS, US) are printed in the front matter, so you know exactly what a supersession means. For example, a “Y” means unconditional compatibility; a “P” means the original part is prohibited and you must use the alternative. You don’t get that from an online parts cross-reference.

Frequently Asked Questions

Does this catalog cover the entire ZX160LC machine?

It covers the hydraulic equipment, precision parts, and attachment cylinders. The engine and electrical parts are in separate manuals.

Can I use this to order parts from a dealer?

Yes. Provide the part number, part name, quantity, and machine serial number from the catalog’s product identification field. Dealers require OEM numbers for warranty claims.

What is the difference between a parts catalog and a service manual?

A parts catalog gives you the exploded view and part numbers. A service manual gives you disassembly, assembly, and torque specs. You need both. This is the parts catalog only.

Are there torque values in this catalog?

No. Torque specifications are in the service manual. The parts catalog focuses on identification and interchangeability.

If you’re ordering parts for a ZX160LC, you want the page that matches what’s in the hydraulic bay. This catalog gives you the factory breakdown for every pump, motor, valve, and cylinder assembly.
